      r'''This function handles calculation of one-phase fluid pressure drop
      due to acceleration for flow inside channels. This is a continuous 
      calculation, providing the differential in pressure per unit length and
      should be called as part of an integration routine ([1]_, [2]_).
      
      .. math::
          -\left(\frac{\partial P}{\partial L}\right)_{A} = G^2
          \frac{\partial P}{\partial L}\left[\frac{\partial (1/\rho)}{\partial P}
          \right]- \frac{G^2}{\rho}\frac{1}{A}\frac{\partial A}{\partial L}
  
      Parameters
      ----------
      m : float
          Mass flow rate of fluid, [kg/s]
      D : float
          Diameter of pipe, [m]
      rho : float
          Fluid density, [kg/m^3]
      dv_dP : float
          Derivative of mass specific volume of the fluid with respect to 
          pressure, [m^3/(kg*Pa)]
      dP_dL : float
          Pressure drop per unit length of pipe, [Pa/m]
      dA_dL : float
          Change in area of pipe per unit length of pipe, [m^2/m]
  
      Returns
      -------
      dP_dz : float
          Acceleration component of pressure drop for one-phase flow, [Pa/m]
          
      Notes
      -----
      The value returned here is positive for pressure loss and negative for
      pressure increase.
      
      As `dP_dL` is not known, this equation is normally used in a more 
      complicated way than this function provides; this method can be used to 
      check the consistency of that routine.
      
      Examples
